Single-ply replacement: TPO and PVC
Most Houston low-slope roofs end up using TPO or PVC, two types of single-ply membrane roofing. TPO's reflective surface cuts cooling costs through a hot Gulf Coast summer, and its heat-welded seams hold up better than glued seams in this humidity. PVC is the better choice where grease, chemicals, or restaurant kitchen exhaust would damage TPO. We choose the membrane thickness, insulation strength, and attachment method based on your deck type and wind zone, then test the finished roof with water before handing it over.
Restoration instead of replacement — when the numbers work
A silicone restoration coating can add ten to twenty years to a roof that's still in decent shape, for a fraction of the cost of tearing it off. It also counts as a maintenance expense instead of a big capital project. The deciding factor is whether moisture is trapped inside, which is why we bring in an imaging partner to run thermal moisture mapping first. This scan uses infrared cameras to find wet spots under the surface. Wet insulation gets cut out and replaced, or the building gets a full replacement — we'll tell you which, in writing, before anyone quotes a coating.
NDL warranties and roofer-of-record programs
For institutional owners, the warranty itself is a valuable asset. No Dollar Limit (NDL) coverage puts the manufacturer behind both material and labor, with no cap on repair cost. But it's issued by the manufacturer, not by P91, and only after the system is installed to spec and inspected. If an owner wants that coverage, we install to the manufacturer's published standard and help with the paperwork — approval still comes from the manufacturer. Owners with several Houston buildings usually keep us on as their main roofing contractor, with scheduled preventative maintenance, which also helps keep the manufacturer's warranty in force.
Zero business interruption
We never leave a roof open overnight. We tear off and seal each section the same day, keep dock doors and entrances usable, set up staging areas away from customer parking, and schedule the noisy work around your operating hours. On occupied apartment communities we also send resident notices and work building by building, so management isn't fielding surprise calls.
Leaks, storm damage and diagnostics
Water often travels under a membrane before it shows up as a stain on a ceiling tile, so we trace leaks to their real source with video diagnostics and moisture scanning, instead of just patching the stain. For urgent leaks, our local restoration partner handles the immediate response and any interior water damage. P91 handles finding the cause and making the permanent roof repair.
Across Greater Houston and north
We work across the full metro area and the northern corridor: The Woodlands, Conroe, Spring, Tomball and Magnolia. Have a project to bid? Send it through our RFP intake and we'll respond with a detailed proposal.
FAQ
What size commercial roofs does P91 take on in Houston?+
From single-tenant retail buildings of a few thousand square feet up to multi-building industrial and apartment portfolios of several hundred thousand square feet. For larger projects, we act as your main roofing contractor and schedule the buildings across budget years.
Can the work happen without interrupting our operations?+
Yes. We remove the old roof and seal each section the same day, so no part of the roof is ever left open. We keep dock doors, entrances, and parking lanes usable, and schedule the loudest work outside your busiest hours. Working on occupied buildings is normal for us.
What is an NDL warranty and do you provide one?+
A No Dollar Limit (NDL) warranty is issued by the membrane manufacturer, not by P91. It covers both material and labor for leak repairs with no cap on the repair cost. If an owner wants one, we install the roof to the manufacturer's exact spec and help with the inspection and paperwork — but the manufacturer decides whether to approve and issue the warranty.
Should we replace the roof or restore it with a coating?+
It depends on how much moisture is trapped in the roof already. If the insulation is dry and the membrane is in good shape, a silicone coating can add 10 to 20 years of life for much less than a full replacement. If moisture is trapped inside, coating over it just hides the problem. That's why we scan the roof first before recommending either option.
Do you handle insurance and storm damage claims on commercial buildings?+
We document the damage with drone photos, moisture scans, and a written scope, so your insurance carrier and adjuster have solid evidence. We don't negotiate claims for you, and we tell you honestly whether the damage is likely covered.
How quickly can you get on our roof?+
Call (281) 948-2208 and we'll schedule a site visit, usually within a few business days across Greater Houston. We follow up with a written condition report and a budget number.
